Risk Ratio

The risk ratio is a measure used in studies to compare the likelihood of a specific event happening in two different groups. For example, if one group has a 10% chance of developing a condition and another group has a 5% chance, the risk ratio is 2, meaning the first group is twice as likely to develop that condition. It helps to understand how strongly a factor may be associated with an outcome, providing insight into potential risks related to exposure or treatment.
